"Yes, I have talked before about ending my career at Barcelona -- but we don't know because football is moving fast and you never know about tomorrow," Toure told beIN Sports in a TV interview on Tuesday night. "My agent, Dimitry, is always on the phone and he knows what he has to do because I trust him a lot.

"The main thing now is just to try and focus on the World Cup and he knows what he has to do because we were always open about everything and I am able to talk with him for a couple of days now.

"Because of the brilliant season Manchester City have had, everybody is talking about me and everything is open and we don't know tomorrow."

Toure's agent, Dimitry Seluk, told The Sun on Tuesday that his client was unhappy that City's owners had shown "disrespect" by apparently snubbing Toure's birthday while the club were on tour in Abu Dhabi.

"He got a cake but when it was Roberto Carlos' birthday, the president of Anzhi gave him a Bugatti," he said. "I don't expect City to present Yaya with a Bugatti -- we only asked that they shook his hand and said: 'We congratulate you.' It is the minimum they must do when it is his birthday and the squad is all together.

"I hear one newspaper has written that City congratulated him from Twitter but this is a joke. It is better they don't put anything on Twitter if they are not saying anything to him.

"The club's owners ate a 100kg cake after winning the Premier League this season but when they and the players were all together, none of them shook his hand on his birthday. It shows they don't care about him.

"Of course Yaya is upset about this. If this happened to you as a journalist in the BBC and nobody shakes your hand, you will say bye-bye and go to work for somebody else. It is normal."
